我想从我的jar中读取资源,如下所示:

File file;
file = new File(getClass().getResource("/file.txt").toURI());
BufferredReader reader = new BufferedReader(new FileReader(file));

//Read the file

并且它在Eclipse中运行时工作正常,但是如果我将它导出到jar中运行它就会出现IllegalArgumentException:

Exception in thread "Thread-2"
java.lang.IllegalArgumentException: URI is not hierarchical

而且我真的不知道为什么,但经过一些测试我发现如果我改变了

file = new File(getClass().getResource("/file.txt").toURI());

至

file = new File(getClass().getResource("/folder/file.txt").toURI());

然后它的工作正好相反(它适用于jar而不是eclipse).

我正在使用Eclipse,我的文件夹在一个类文件夹中.

当我尝试在Jenkins中运行maven作业时,构建不成功.

控制台中的错误消息显示以下内容:

有下面的代码,我怎么知道execute()方法是否导致插入或更新？:

Connection c = DriverManager.getConnection(connectionString);

PreparedStatement st = c.prepareStatement("INSERT INTO `table`(`field1`) VALUES (?) ON DUPLICATE KEY UPDATE id=LAST_INSERT_ID(id);");

st.setString(1,"some value");
st.execute();

提前致谢.
